Rebeccah upgrades her sleepwear

After dinner, as you and Rebeccah are heading up the stairs to change into your nighties, her mother calls out .

"Rebeccah, I feel it's time for you to have something more mature to wear to bed," she says. "I bought you something. Why don't you try it on so we can see how it fits?"

She hands Rebeccah a bag from the lingerie store.

"Thank you mommy!" she says, clearly excited about the gift.

As you are finish putting on your own nighty, Rebeccah knocks and comes into your room.

She is wearing a sheer babydoll nightdress and a matching pair of tiny thong panties. The only part of the outfit that isn't completely sheer is the top that covers her breasts, but her nipples are still clearly visible.

"Wow!" you say.

"You like?" she asks, smiling. She is blushing but seems to be enjoying your reaction.

Rebeccah sits on your bed and leans back, spreading her legs.

"Look," she says seductively. "The panties are completely see through."

Indeed, from your angle, you can see every detail of her beautiful, shaved pussy.

"I'm going to have so much fun teasing you and flashing my pussy," she says with a wicked smile.

Downstairs, Rebeccahs mother inspects her and declares it a perfect fit.

"And it looks so sexy on you," she says, standing back and looking. "Don't you agree, Sweet Boy."

"Yes, mommy," you say, feeling suddenly shy. Rebeccah's mother is herself wearing something black and sheer. The light is a little dim, but you can still see the outline of her much bigger breasts and nipples beneath the fabric, and of course her pussy is not shaved, but neatly trimmed.

Rebeccah's mother gives you a knowing wink, then saunters into the kitchen to prepare your hot chocolate. Her full ass is completely bare save for a black string, the back of her panties. Rebeccah, nudges you in the ribs, and you jump. You look over at her guiltily, but she is smiling back at you.

"Pervert," she whispers, then pulls a blanket over the both of you.

Under the blanket, she pats the front of your diaper.

"Too bad this is in the way," she whispers. "I guess you'll have to tease me instead."

She takes your hand and puts it beteween her legs.

"Only through my panties," she warns. "And don't make it obvious."

Your fingers trace the outline of her pussy, lightly sliding against her slit from the bottom to the top, where you brush against her clit. Her breathing gets heavier and you are starting to get really aroused as well. You are interrupted by the arrival of hot chocolate, but then when you settle back into the blanket to sip, you let your hand drift back between her legs.

A few times, she seems to get too excited and pinches your hand between her thighs, but then, after a few moments, allows you to continue. Finally, you are getting sleepy and her mother notices.

"It looks like it's time for bed," she says, looking up from her book. "Rebeccah, why don't you take him up?"

You are led, groggy and almost stumbling, up the stairs. As you are laying back in your bed, Rebeccah, leans down and gives you a sexy, lingering kiss.

"You have me so turned on right now," she whispers. "I'm going to go fuck myself with that vibrating cock now. I wish you were awake enough to watch me."

But you are far too tired and you drift off to sleep.

You have strange dreams about Rebeccah in her lingerie, and she is playing with her dildo. She is working it in and out of her pussy, oblivious to anything else. But then, because dreams work that way sometimes, you aren't sure if it is a dildo or a real cock. For some reason, the thought of Rebeccah being pounded by a real cock arouses you even more.

The last thing you remember about the dream is Rebeccah looking into your eyes as she comes. For some reason, in your dream, you aren't jealous at all, even though you are sure it is a real cock that made her come, and that it wasn't yours.
